WORCESTER — Authorities believe a Gardner woman wanted on charges stemming from a June 21 fatal shooting in Fitchburg is on the run with her 1-month-old baby.

A warrant was issued Thursday for the arrest of 25-year-old Ashley Fruguglietti of 365 Elm St., Apt. 24, Gardner, after a Worcester County grand jury returned indictments charging her with being an accessory, after the fact, to murder and misleading law enforcement.

The charges relate to the June 21 shooting death of Luis R. Rodriguez, 26, in his third-floor apartment at 82 Marshall St., Fitchburg. Warrants were issued earlier last week for the arrest of two men on charges of murder, home invasion and armed assault in a dwelling in connection with the slaying.

The two men, both alleged to have gang ties, are Dax A. Gibson, 36, also of 365 Elm St., Apt. 24, Gardner, and Dinkue Brown, 27, of 33 Adams St., Fitchburg. Mr. Gibson is Ms. Fruguglietti's boyfriend and the father of her child, according to law enforcement officials.

All three suspects remain at large, and District Attorney Joseph D. Early Jr. said Monday that they are believed to have fled the state. Mr. Early also said investigators believe Ms. Fruguglietti has her 1-month-old child with her and that she is either with Mr. Gibson or on her way to meet him.

He said the state Department of Children and Families had been notified.

"It's a tenuous situation, at best, when you think of the needs and wants of a 1-month-old baby. We have grave concerns for the child," Mr. Early said.

Mr. Rodriguez was found about 2 p.m. June 21 bleeding on a neighbor's porch and was taken to HealthAlliance Hospital — Leominster Campus, where he was pronounced dead a short time later. Authorities said he was assaulted in his apartment and apparently fled the attack and collapsed on a rear porch at 68 Marshall St., Fitchburg.

Based on the nature of his injuries, investigators initially believed Mr. Rodriguez had been fatally stabbed, according to Mr. Early. He said it was later determined that the victim had been shot three times.

Mr. Early said last week investigators did not believe the attack was random, but declined to discuss a possible motive.
